Celebrate a 6th birthday with this stitched under the sea invitation that turns the party into an adventure from the very first tap. The design comes straight from the printed card: chunky stitched-patch lettering in rainbow felt colours and painterly a blue whale, a sea turtle, a seahorse, coral, starfish, seashells, seaweed, bubbles, waves, all on bright white paper so the colours pop on any phone. The guest page opens with the birthday child's name sewn on letter by letter, then the age, the date and the host, before the invitation card itself appears on a stitched felt mat with the whale peeking at the mat's bottom-left and the turtle at the bottom-right. Guests scroll past a bunting seam to the party details, a note from the host, a felt band that shouts the age, a felt-pocket countdown that ticks down to the party in days, hours, minutes and seconds, a map with one-tap directions and add-to-calendar buttons, and finally the seahorse mascot above a felt reply patch where they RSVP yes, no or maybe in seconds. Every reply lands in the host dashboard with a live guest list, headcounts and reminders, so nobody has to chase replies by text. The matching print bundle includes a welcome sign, a photo booth frame, a guest book page, a stitched under the sea colouring sheet and party bingo, all in the same painterly style. Built for a 6th birthday and ready the moment you add your details. Perfect for backyard parties, playroom parties, park picnics and any little guest of honour who loves a blue whale, a sea turtle, a seahorse. Share it by link, text or email; it reads perfectly on a phone and opens up on a laptop, and every detail — the name, the age, the date and time, the venue, the host message and the RSVP deadline — is editable in minutes.
